General Functions
5. General Functions
The panel function is congurable by the jumper links JP1.
Jumper Removed Default setting
JP1 – 1 MODE SP Mode EV Mode
JP1 – 2 BAT Battery Enabled Battery Disabled
In SP Mode the panel functions as a basic natural AOV panel
like the legacy SP-300 panels.
In EV mode the panel functions as an addressable interface
panel for the advanced shaft system accepting Databus
commands from a master panel.
5.1. Battery Back-Up
Jumper JP1 – 2 selects if batteries are installed and connec-
ted.
● When enabled the charging unit will automatically manage
and recharge the batteries. The charging unit will monitor
and indicate any faults or warnings with the power supply
and batteries.
● When disabled the battery back-up monitoring and any
associated faults are disabled.
5.2. Sleep Mode
When operating on batteries in the event of a mains failure the
panel will go into a sleep mode function to preserve battery
life. In sleep mode the panel will disable daily ventilation
functions and close the vents before switching o the vent
output power and sensor supply terminal ES.
During sleep mode the Databus interface will stay alive and
continue to communicate.
Once the mains power supply returns healthy the panel will
automatically resume back to normal operation and restart
daily ventilation functions.
Sleep mode will be activated after a ‘Ventilation time after
mains failure’ delay period following a mains failure. If the
vent is open for daily ventilation the vent output power will
automatically close the vent for 2 minutes before entering
sleep mode. The timer is programmable via SIMON LINK.
If an alarm or override condition is triggered during sleep
mode, sleep mode is cancelled, and all the outputs energise
and operate to the alarm condition as required.
When an alarm or override condition is reset when operating
on batteries the vent output power will automatically close the
vent for a ‘Ventilation time after reset’ period before entering
sleep mode. The timer is programmable via SIMON LINK.
Programmable Parameter Range Default setting
Ventilation time after mains failure 0..3600 sec 30 sec
Ventilation time after reset 0..180 sec 70 sec
5.3. FAS Input Signal
A re alarm signal on FAS1 and FAS2 is detected by an open
circuit across the terminating resistor. Detecting a re alarm
signal by short circuit across the terminating resistor is pro-
grammable via SimonLink to indicate a fault condition only.
The input signal is reset when the terminating resistance is
measured within a tolerance.
Programmable Parameter Range Default setting
Fault only on wire break Yes / No No
5.4. Open Vent Delay
An OPEN command delay time is programmable before swit-
ching on the open vent output power. When an OPEN com-
mand is triggered the vent output power switches o until the
‘Open Delay’ time expires. The delay time is programmable
via SimonLink. When set to zero the delay timer defaults to
0.5 seconds to break the vent output power as a safeguard
when switching the output polarity.
Programmable Parameter Range Default setting
Open delay 0..3600 sec 0 sec
5.5. Close Vent Delay
A CLOSE command delay time is programmable before swit-
ching on the close vent output power. When a CLOSE com-
mand is triggered the vent output power switches o until the
‘Close Delay’ time expires. The delay time is programmable
via SimonLink. When set to zero the delay timer defaults to
0.5 seconds to break the vent output power as a safeguard
when switching the output polarity.
Programmable Parameter Range Default setting
Close delay 0..60 sec 0 sec
5.6. Vent Output Retriggering
When the vents OPEN in an alarm or override condition the
vent output power can be cycled open then close sever-
al times to help release sticking vents before continuously
opening. This function is programmable via SIMON LINK.
Programmable Parameter Range Default setting
Retriggering Yes / No No
5.7. Signal Contact
The relay signal contact has separate operating functions
for EV mode and SP mode programmable via SIMON LINK.
Factory default settings are:
● SP Mode (Alarm triggered) – Relay operates when panel
is in alarm
● EV Mode < remote control > – Relay operates on
Databus Relay command
Programmable Parameter Range Default setting
Delay O..1 hour O
Holding time Unlimited..1 hour Unlimited
Inverse logic Yes / No No
